🤷 Splitting long runs? Really?


Brought to you by:

Hi runners, 👋🏼

Katelyn here with newsletter #635!

We’re wrapping up an incredible weekend here at the TCS Toronto Waterfront Marathon — and what a weekend it's been! I've included some of the coverage we've been busting out below, and we'll share our live show from the expo soon.🏃‍♀️🇨🇦

Today, as well as the TCS Toronto Waterfront Marathon, there were two other big marathons scheduled: TCS Amsterdam (more info on that below), and the Cape Town marathon. Just in the past few hours, we've heard that the Cape Town marathon has been called off due to high winds. When we know more we'll cover it in tomorrow's newsletter.

Meanwhile, here's what I've got for you today:

  • Marathon interval training: How to add it to your marathon prep: My favorite part of training! Learn how to build speed safely and effectively with interval workouts tailored to your goals.
  • Is it OK to split up long runs? Short on time? Here’s when it’s fine to divide your long runs — and when it’s better to power through in one go.
  • 🍼 How to balance running and parenting: 13 real-life tips that actually work: Sarah and Thomas share how they’ve managed to keep training strong through the chaos of family life — with practical, honest advice any parent-runner can use.
  • 🔢 The Strava struggle: Why your run can’t end at 4.99 miles: Does that extra .01 matter?
